DEMOUNTABLE RIM.

Specification of Letters Patent.

Patented Mar.9,19ec.

Application filed September 18, 1919. Serial No. 324,533.

To all whom t may concern.' y

Be it known that I, FRED H. VAN LoozEN, a citizen of the UnitedStates, residing at Lakewood, in the county ot Cuyahoga and State of Ohio, have invented certain new and useful Improvements `inv Demountable Rims, of which the following is a specilication.

My invention relates to improvements in demountable rims, and more particularly to that class or type whirh are used in connection with motor vehicle wheels and pneumatic tires. y

The primary object of the invention is to provide a generally improved deinountable rim of this class, which will be exceedingly simple in construction, cheap of manufacture and eiiicient `in use.

A further and very important object of the invention is the provision of a demountable rim adapted to receive and to be readily attached to or detached from any ordinary pneumatic tire of either the straight sided or the clencher tvpe, and without the use of any special tools.v

A still further and very important object of the invention is the provision of an improved two-part or circumferentially split demountable rim having improved means for detachably connecting and interlocking the parts together in assembled position.

With the above mentioned and other ends in view. the invention consists in the novel construction. arrangement and combination of parts. hereinafter described, illustrated in some ot its embodiments in the accompanving drawings. and particularly pointed out inthe appended claims.

Referring to the drawings, forming a part ot' this specification, Fixture 1, is a side elevation of a tire rim ot the straight side type detached from the vehicle wheel and tire.

Fig. 2.a fragmentary cross sectional view Vof the same. attached to a tire of the straight sided heel type.

Fig. 3. a similar view oi the same attached to a tire'of the beaded or clencher type.

Fic'. 4, an enlarged fragmentary disassembled view of the interlocking tongue and recess portions of the same before bringing the rim sections together for interlocked assembled position.

Fig. 5. a cross sectional view taken on line 5-5. of Fig. 4.

Fig. 6, a fragmentary perspective view of the inner or recess portion of one of the rim sections.

Fig. 7, a similar view of the interlocking tongue or lug portion of the same.

. Fig. 8, a perspective view of one ot' the rim sections detached.

Similar numerals 0f reference designate like parts throughout all the figures ot' the drawings. i Y

The improved demountable rim is adapted to be mounted upon and be attached to any suitable or convenient vehicle wheel and may be secured thereto in any convenient and suitable manner.

As a convenient means of readily attaching the tire rim to or detaching' the same from a pneumatic tire 1, the tire vrim is preferably circumferentially divided by being made up in the form of abutting rim sections 2, said rim sections being preferably in the Jform of companion sections of like form meeting or abutting at the median or central portion of the rim and terminating at their sides in tire engaging flanges 2a. The tire engaging flanges 2a, may be either of the straight sided type for attachment to a tire ot the straight sided type, as indicated in Figs. l and 2, and Figsyf to 8, inclusive of the drawings` or it desired may be inthe -'orm ot clencher fianges for attachment `to a tire of the clencher type, as shown in Fig. 3, of the drawings.

As a means of readily attaching the rim. sections 2, to each other and detaching the same from each other in the act ot assembling and disassembling such parts with respect to the tire casing 1, and particularly as a means of interlocking the companion rim sections together to prevent relative lateral or circumferential movements when secured to the tire casing and mounted upon thevehicle wheel, the rim sections 2. are

. provided with improved connecting and in- The cross or conneetingmembers 3, are preferably arranged on the companion rini sections 2, in diametrically opposite relation to each other and are preferably secured beneath the same in any suitable and convenient manner, as for eXample,#by means of rivets or fastening` elements 3"',

and as a means of automatically connecting the cross or connecting members 3, to the adjacent or opposing rim section, the coupling,membersy 3, are preferablyprovided at their free ends With upwardly extending projections or thrust pins 3d, adapted to enter correspondingly formed and located pin receiving` openings 3G. As a further means of facilitating the assembly ot the partsA the projecting ends of the coupling members 3, are preferably of spring or resilient material and the ends of the projections or pins 3d, are preferably slightly beveled, as shown most clearly in Fig. 5, and if desired the ends of thel coupling or connecting members 3. may likewise be si1nilarly beveled as at 3f.

As a means of causingthe projections or pins 3d, to be brought into registry with the openings 3e, when the companion rim sections 2, arebrought together in securing` a tire casing thereon, and particularly as a means of preventing circumferential movement relatively of the rim sections when assembled, the sides of the key or lug members 3a, are preferably slightly beveled or tapered toward the Jfree ends of the key members and. so likewise the sides of the recesses 3?, adapted to receive the same.

When itis desired to detach the rim sections for detachment from the tire casing, the free ends of the cross or connecting members 3, may be bent inwardly away 'from the connected rim sections, soas to detach Y the projection or stud pin from the pin opening and moving the sections slightly out of assembled or registered position, and this being done successively on the various cross members until all are removed, the rim sections maybe then readily detached.

From the foregoing description, taken in connection ivith the accompanying drawings. the construction, operation and advantages of my invention will be readily understood.

Having thus described some of the einbodiments of my invention, what l Aclaim and desire to secure by Letters Patent, is.-

l. A tire rim, comprising circumferentially split rim sections provided on their abutting` sides with interlocking transversely extending tapered tongue and recess members, said tongue members being resilient and provided with adially extending pins removably entering corresponding openings iormed in the adjacent rim section, said tapered tongue and recess members serving to guide said pins into said openings when the rim sections are asscm* bled.

2. A tire rim, comprising` lianged like rim sections provided with subjacent resilient cross coupling members carrying pin and shoulder projections detachably seated in corresponding pin openings and recesses in the opposite rim section, said pin openings being opposite said recesses and the latter and said shoulders being tapered to centralize said pin projections in said openings when said rim sections are brought together.

3. A. demountable rim 'tor vehicle Wheels, comprising flanged rim sections provided on their under sides with spring coupling inembers extending across the abutting portions thereof` and carrying laterally extending tapered key members, said coupling members being also provided with radial projections adapted to enter corresponding openings in the opposite rim section and said rim section being` provided with tapered recesses adapted to receive said tapered key members and `guide said radial projections into said openings.

In testimony whereof I have ailixed my signature.
